Product Description
Fibre Core Conformal Coated Wirewound Resistor - SPP Series
The SPP Series Fibre Core Conformal Coated Wirewound Resistors are designed for applications requiring reliable fusing capabilities, with UL1412 recognition. These resistors offer a wide range of resistance values and are available with high TC's upon request. They are suitable for both weldable and solderable lead applications, providing flexibility in assembly. The conformal coating ensures protection and durability, making them suitable for various environmental conditions. The flameproof fusible nature, indicated by a blue band, adds a critical safety feature for overload protection.
